This book appeals to adventure seekers and fans of the supernatural, blending elements of ghostly encounters with a magical world reminiscent of Harry Potter. It invites readers into a captivating narrative filled with thrilling escapades and enchanting mysteries. The story promises to engage those who believe in the unseen and are eager for a journey that intertwines reality with the extraordinary.
Tensors and methods of differential geometry are very useful mathematical tools in many fields of modern physics and computational engineering including relativity physics, electrodynamics, computational fluid dynamics (CFD), continuum mechanics, aero and vibroacoustics and cybernetics. This book comprehensively presents topics, such as bra-ket notation, tensor analysis and elementary differential geometry of a moving surface. Moreover, authors intentionally abstain from giving mathematically rigorous definitions and derivations that are however dealt with as precisely as possible. The reader is provided with hands-on calculations and worked-out examples at which he will learn how to handle the bra-ket notation, tensors and differential geometry and to use them in the physical and engineering world. The target audience primarily comprises graduate students in physics and engineering, research scientists and practicing engineers.
Do assessment topic and task choice affect the quality of the test-takers' speaking performance?
Focusing on the assessment of speaking abilities, this research study explores how topic selection impacts the oral performance of Vietnamese faculty in English. It investigates the effectiveness of various oral assessment instruments and identifies the relevance of general versus academic field-specific topics. The findings reveal no significant difference in performance between the two types of topics, suggesting important implications for language testing and highlighting the training needs of faculty in spoken English for academic settings.
